我在我的頁面上有一個我想優化的深入貼圖。 現在我正在加載每個「深入」地圖,即使它沒有被點擊。優化JavaScript DrillDown代碼
Here是一個示例,顯示如果狀態被點擊,數據如何加載。我想實現這一點。
但是,這是我的代碼,正如你所看到的,即使地圖沒有被點擊,我也會加載所有向下鑽取的jsons。在我的例子中,我只有2個向下鑽取選項,但在我現實生活中的問題中,我有15個,所以它確實減慢了一切。
所以這是我的代碼:
從generate_json_region_1.php[{"drilldown":"a","name":"region 1","value":"1","path":""},{"drilldown":"b","name":"region 2","value":"2","path":""}]
JSON:
// get main map
$.getJSON('json/generate_json_main_map.php', function(data) {
// get region 1 map
$.getJSON('json/generate_json_region_1.php', function(first_region) {
// get region 2 map
$.getJSON('json/generate_json_region_2.php', function(second_region) {
// Initiate the chart
$('#interactive').highcharts('Map', {
title: {
text: ''
},
colorAxis: {
min: 1,
max: 10,
minColor: '#8cbdee',
maxColor: '#1162B3',
type: 'logarithmic'
},
series: [{
data: data,
"type": 'map',
name: st_ponudb,
animation: {
duration: 1000
},
states: {
//highlight barva
hover: {
color: '#dd4814'
}
}
}],
drilldown: {
drillUpButton: {
relativeTo: 'plotBox',
position: {
x: 0,
y: 0
},
theme: {
fill: 'white',
'stroke-width': 0,
stroke: 'white',
r: 0,
states: {
hover: {
fill: 'white'
},
select: {
stroke: 'white',
fill: 'white'
}
}
}
},
series: [{
id: 'a',
name: 'First',
joinBy: ['hc-key', 'code'],
type: 'map',
data: first_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}, {
id: 'b',
name: 'Second',
joinBy: ['hc-key', 'code'],
type: 'map',
data: second_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}]
}
});
});
});
});
從generate_json_main_map.php JSON
[{"name":"Place 1","key":"place.php?id=1","value":"1","path":""},{"name":"Place 2","key":"place.php?id=2","value":"2","path":""}]
這是我試圖讓阿賈克斯調用並行加載,但地圖不加載,我只得到coloraxis。
$(function() {
$.when($.getJSON('json/generate_json_main_map.php'), $.getJSON('json/generate_json_region_1.php'), $.getJSON('json/generate_json_region_2.php')).done(function(data,first_region,second_region){
$('#interactive').highcharts('Map', {
title: {
text: ''
},
colorAxis: {
min: 1,
max: 10,
minColor: '#8cbdee',
maxColor: '#1162B3',
type: 'logarithmic'
},
series: [{
data: data,
"type": 'map',
name: st_ponudb,
animation: {
duration: 1000
},
states: {
hover: {
color: '#dd4814'
}
}
}],
drilldown: {
drillUpButton: {
relativeTo: 'plotBox',
position: {
x: 0,
y: 0
},
theme: {
fill: 'white',
'stroke-width': 0,
stroke: 'white',
r: 0,
states: {
hover: {
fill: 'white'
},
select: {
stroke: 'white',
fill: 'white'
}
}
}
},
series: [{
id: 'a',
name: 'First',
joinBy: ['hc-key', 'code'],
type: 'map',
data: first_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}, {
id: 'b',
name: 'Second',
joinBy: ['hc-key', 'code'],
type: 'map',
data: second_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}]
}
});
});
});
我可以看到,jsons被加載,並沒有顯示由螢火蟲JS錯誤。
任何人,任何建議? – DJack
沒有完全花時間來理解這段代碼,但是你不能點擊某個區域,發送該區域的「id」並只獲得該特定區域的向下鑽取數據? –
您可以嘗試並行處理這三個請求,這可能會有所幫助。 – Whymarrh
